IMPROVEMENT IN DlTCHlNG-PLOWS.

Specification forming part of Letters Patent No. 29,357, dated July 31, 1860.

- To all whom it. may concern:

Be it known that I, JAMES BROOKS, of the town of Romulus, county of Seneca, and State of New York, have invented a new and useful Ditching-Plow; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification.

As a basis of my improvement or invention I adopt the old-fashioned frame of the shovelplow, the beam, post. and handles shown at B, beam P, post, and H H handles, the last adj ustable by meansofsegment I, which receives a pin that fastens the handles at a given height on this frame. I place an adjustable clevis, 0, so as to change, when necessary, the pointof traction. With the arms A A A, connected with the the beam at X X, I bolt at It a pulley, R. These arms and the pulley are adjustable. I also construct of iron or steel a peculiarlyshaped colter-sha-re, as seen at S S S, S "beshaped like a common small plowshare. Thisplowshare I fasten to the post with clamps,

as seen at d d D D and secured by nuts N N. This colter-share is thus adjustable. Opposite this share, on the reverse of the post, I place a guide-bar, G G, shaped like an inverted T, or simply straight without the arms, made of boiler-iron, wood, or any other suitable material. This guide-bar I use simply as a guide bearing against the side of the progressing ditch, or by makingitsharplsufterit to cut as well as guide. This guide-bar is also slightly bent, so as to clear the ditch at its upper part.

To use this plow, I adjust the ground wheel or pulley at about four inches above the bottom of the share and pin it fast. The guide-bar I also place above ground at first. I then cut a furro\v,and,coming back on the opposite side of the begun ditch, I out again. Shovelers fol-
